October 5, 2021 (San Diego) -- The San Diego County Department of Environmental Health and Quality (DEHQ) has issued a General Rain Advisory to avoid water contact at all coastal beaches and bays due to recent rainfall. Swimmers, surfers and other water users are warned that rain brings urban runoff, which can cause bacteria levels to rise significantly in ocean and bay waters, especially near storm drains, creeks, rivers, and lagoon outlets. Urban runoff may contain large amounts of bacteria from a variety of sources such as animal waste, soil, and decomposing vegetation. Bacteria levels can remain elevated after a rainstorm depending upon the intensity of the storm, volume of runoff and ocean conditions.
